Slade 3300W Pump and Valve Packing

Slade 3300W Pump and Valve Packing

Slade’s Cost Effective Pump & Valve Packing for higher pressures. Each individual strand of graphite foil is reinforced with Inconel® wire that is shrouded with high strength carbon fiber.

Typical Composition

• Main Component: Graphite, Carbon
• State of Main Component: Expanded
• Wire Reinforcement per Yarn: Up to 2 % Weight

Working Parameters

• Maximum Working Temperature: 1800 ºF, 1000 ºC
• Maximum Pressure (Valves): 5000 psi, 345 bar
• Chemical Resistance (Except in Strong Oxidizers): 0 to 14 pH

Benefits

Slade manufactures its own patented graphite foil yarns to achieve these standards.

Advantages

• Works well on smoothly or worn sleeves
• Difficult to over tighten

Features

• Each Braided Yarn Reinforced with Carbon Fiber (600,000 psi Tensile Strength)
• No special end-rings required. Carbon-Corners on Each Ring of 3300G Provide Excellent Anti-Extrusion and Wiper Action. Good to 5,000 psi (345 bar)
• Reduces inventory and cost:
  • By Eliminating Die-Formed Rings for Each Valve
  • By Having a Few Standard Sizes for All Valves
  • If a Leak Develops, Just Add a Ring
• Highly Polished Surfaces are not Required (Finishes Between 8 to 30 RMS are Fine)
• No Lubricants, Grease or Impregnants that can be Squeezed, Washed or Cooked Out

Applications

• Pulp and Paper Mills
• Nuclear, Fossil and Hydroelectric Power Plants
• Waste Water Treatment Plants
• Reciprocating Pumps
• Cooling Tower Pumps
• Vacuum Pumps
• River Water Pumps
• Fire Pumps
• Auxiliary Pumps
• Reciprocating/Plunger, Wastewater
• Steam and Ammonia Pumps
• Oil Well Sucker rods, etc.

Advantages

Minimizes or Virtually Eliminates Leakage! 
Due to its patented construction of  natural, expanded graphite yarns,  Slade 3300G turns the stuffing box into a heat sink, conducting heat away from shaft, in many applications, eliminating expensive leakage previously needed to cool the stuffing box.

Can Be Operated Flush-Free in Most Applications
Slade 3300G conducts heat away from the shaft/sleeve, in most cases making flush unnecessary. If media has particulate contamination, a very mild flush should be all that is requires.

No flush-water translates into:

• Exceptional savings, typically 1/2 cent per gallon, or $13,000 annually (U.S.) (based on 5 GPM flush system)
• No fear of flush-water system becoming plugged or experiencing loss of pressure

Reduces Inventory and Cost

• By eliminating die-formed rings (cut-rings work fine)
• Handles most medias, 1-14 pH, eliminating many styles of packing
• In many applications, no need to remove old packing, just add a ring
• Lasts 4 to 6 times longer than traditional pump packings

Worn Shafts and Sleeves Easily Sealed 
Conforms to the geometry of the stuffing box and shaft.  Seals most worn sleeves.

Pump Sealing Technology

Why Traditional Packings Fail

How a Stuffing Box Should Look When Completely Packed Using Traditional Packings

Traditional packings are mostly fiber with added lubricants that can be squeezed, cooked or washed out, resulting in out-of position lantern rings, over-compressed packing and sleeve wear.

Slade Packed Centrifugal Pumps: Typical Stuffing Box VERSES Slade Packed Stuffing Box

Typical Stuffing Box:  A typical stuffing box requires leakage and/or flush-water to dissipate heat, creating costly housekeeping problems, loss of product and/or loss of flush-water. Additional rings cannot be added without affecting position of lantern ring

Slade Packed Stuffing Box:  In most applications, a Slade packed stuffing box can be run without flush-water and/or with virtually no leakage.  In many applications, both No-Flush & No-Leak are possible!  Additional rings can be added as needed.

Flush-Free & Virtual Leak-Free Service

Depending on design of equipment and speed of shaft, a permanent split bushing may be installed last (after 3300G Rings).  Please  contact us for a recommendation.

Seals Rotating Equipment 

Whereas most pump packings are largely abrasive fibers with added lubricants that can be squeezed, washed or cooked out, Slade 3300G utilizes the self-lubricating qualities of the very best natural, exfoliated graphite.

Incorporating just enough temperature and chemical resistant ‘carbon fiber’ to make very high tensile strength yarns, Slade’s patented technology allows the braided packing rings to transfer frictional heat away from high speed shaft sleeves, eliminating the need, in most cases, for cooling water.

Since cooling or flushing is not typically required, there is no need for lantern rings.  This eliminates the concern of the lantern rings being adjusted out of position, flush water ports becoming plugged, or sleeve wear caused by the corrosive nature of highly oxygenated water on hardened sleeves.

Pump Applications

Replaces expensive Mechanical Seals at 25% of the cost. Split to install without dismantling the pump

An alternative to machining costly bushings is to utilize Slade’s DSS Sealing System.  No machining, no dismantling of the pump.  Achieve leak-free, flush-free service.  It comes fully unitized, ready to install, and we’ll inform you of the gland compression required. If you follow Slade’s installation instructions, you eliminate fear of over-tightening.

The SLADE DSS sealing system can achieve Mechanical Seal performance at packing costs. Contact Slade for information on the DSS bushings.
